AUTOMOBILE-SNOWPLOW.

I i Specification of Letters Patent. Patented J 11 1921 Applicationfiled October 16, 1918. Serial No. 258,421.

To all whom it may concern Be it known that I, HARRY H. CLARK, a

citizen of the United States, residin at Detroit, in the county ofWayne, tate of Michigan, have invented certain new and usefulImprovements in Automobile-Snowplows; and I do hereby declare thefollowingto be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to new and useful improvements in snow plows andparticularly to snow plows which are arranged for attachment toautomobiles.

One object of the present invention is to provide a noveland improveddevice of this character which can be easily and quickly.

attached to or removed from any automobile and which will clear theroad, ahead of the automobile, of snow.

Another object is to provide a-novel and improved device of thischaracter whereby provide a novel and improved device of this characterwhereby the depth of the snow to be removed can be easily andefiiciently regulated.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompanyingdrawing.

In the drawing:

Figure 1 is a top planview of the front portion of an automobile showingmy "invention applied thereto.

Fig. 2 is a side elevation of the same. Fig. 3 is a vertical transversesectional view taken on the staggered or irregular line 33 of Fig. 1.

Fig. lis a vertical longitudinal sectional view taken on the line 4-4 ofFig. 1.

Referring particularly to the acoompanydrawing, 10 represents the frontaxis of the automobile, 11 the radiator, and 12 the filling tube of theradiator, in connection w1th which my invention is particularly adaptedfor use.

Disposed on the front axle, and secured thereto by means of the U-bolts13, are the furcated, as at 15, and receiving therein the rear end of anarm or link 16. This arm is pivotally connected in the bifurcation sothat said arm will swing in avertical plane, as will be plainly seenfrom an inspection of the drawlng. The forward end of each of the arms16 is pivotally engaged in the bifurcated portion of a bolt 17. A pairof forwardly converging blades 18, which are concavo-convex in crosssection, are disposed in front of the automobile, and each blade plates14, each having its forward end bihas one of the bolts 17 Securedthrough the intermediate portion thereof. Each of the blades has anangle member 19 secured to vthe inner face, slightly in rear of the bolt17, and extending transversely between the blades, and secured to saidanglemembers by bolts 20, ina brace rod 21, said rod holding the bladesin proper position in front of the automobile. The forward ends of theblades are hinged together as at 22, whereby when the U-bolts 13 areremoved the two blades may be folded together for conven: ienceinstoring or shipping. Extending rearwardly from each of the blades, at.

points immediately in rear of the bolts 17, are the arms 23 to whichtheshoes 24 are attached. Each of these shoes has its forward lower portioncurved inthe manner of a sled runner so that it will easily glide overthe snow, and formed on the upper edge of the shoe or runner are thearms 25-. These arms are formed with the longitudinal-series of openings26 for the reception of bolts 27 which also pass through said arms 23,to hold the runners in proper position, and whereby they may be adjustedto I the proper height to raise or lower the scraping blades. Carried bythe forward apex of the device is an eye-bolt 28, and engaged with theeye of said bolt is the forward lower end of a rod 29, the other end ofsaid rod being connected to one end of a coilspring 30. A second rod 31is connected to the other end of the spring and has its remaining endformed witha loop or eye 32 which is engaged on the filling tube of theradiator. turnbuckle 33 is dis posed in the intermediate portion of therod 31 whereby the rod may be adjusted and the tension' of thespringincreased or. de-

tomobile.

' cording to the character-of the 'snow,

whether the same is soft or hard. In light or soft snows the depth wouldbe greater than when the snow is of a dry or'hard character. At theforward end of the scraper there is disposed an arm 34, similar to thearms 23, and adjustably secured to this arm is a runner or shoe 35.

Thus as the automobile is driven forward,

. the scraper blades scrape the snow and dewould have fiect it to thesides of the road, the blades being disposed at such a. height from theground that several inches of snow is left on the road for sleighin Thissnow left on the ground, will be su cient to permit the rear wheelsproperly to drive the automobile, which been hard, or impossible indeeper snow. Thus the device serves a double purpose first, by cleaningenough snow from the road to permit proper tractive action of the drivewheels of the automobile, and second, to leave enough snow on the roadto permit the use of slei hs.

Furthermore, by reason 0 the construction and arrangement of therunners, with the forward ends extending forwardly of the lower edge ofthe moldboard, and being of the automobile to operatev upturned in frontthereof, such runners will encounter any obstruction and'lift themoldboard whereby the moldboard will be prevented from striking suchobstruction.

,It will be understood that this device is also especially adapted foruse with large automobile trucks, in cities to. clean the snow from thestreets, and in this case, the blades will be lowered so as to scrapethe snow entirely from the surface of the.

paving.

What is claimed is:

A snow plow comprising a double moldboard, means for detachablysupporting the plow on the front of a motor driven vehicle,

inwardly extending brackets carried by the inner faces and within theangle of the moldboard of the plow, runneis disposed'in parallelrelation to each other and extending forwardly and rearwardly beneaththe moldboard, vertical stems on the runners ad justably engaged withthe brackets whereby the runners are capable of being raised and loweredto hold the moldboard at different distances above the ground andwhereby various depths-of snow will be left on the EARL W'.
